Standards
- ISO 1133, test method A and B
- ASTM D 1238, test method A and B
It is an affordable tabletop instrument that tests the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of a wide range of thermoplastic raw materials, in the form of granules, strips of film etc, which is particularly useful for quality control tests on thermoplastics.
Features
- The instrument is with panel for a simple and fast input of the test parameters, visualization of test execution and final results. Also, test result can be print out via a built-in printer.
- Both Melt flow rate (MFR) and Melt volume rate (MVR) can be determined through a calibrated die under the effect of a pre-determined force, at constant temperature.
- Piston displacement monitored by encoder; storing and printing whenever necessary.
- It is supplied completely with all the accessories and weights necessary for maintenance and operation.
